Abstract

A new application of genetic algorithms (GAs) for feed point optimization of a coaxial probe fed E‐shape microstrip patch antenna is presented. The GA shows excellent results for finding the best feed point in a given antenna structure. The method of moments is used in this paper, employing Rao‐Wilton‐Glisson basis functions. The simulation results show that the E‐shape microstrip patch antenna performs well at ∼2.11 GHz with the minimum return loss of approximately −17.1 dB. © 2006 Wiley Periodicals, Inc.
